Plastic covers

Plastic covers - versatile solutions for sewage

Plastic covers are a key element of sewage systems.   At Onninen we offer a wide range of these products. Our portfolio includes various types and sizes. PP covers are available in diameters from 315 to 425 mm. We also provide telescopic, solid and openwork models. Our range includes solutions for sanitary and storm sewers. We supply covers that fit smooth and corrugated pipes. The products offered differ in strength classes.

In everyday practice, we observe a growing interest in plastic covers. This is due to their numerous advantages. They are lightweight, which makes transport and assembly easier. They are resistant to corrosion and chemical agents. They do not require maintenance and have a long service life. These features make plastic covers suitable for many applications.

Types and applications of plastic covers

Our offer includes plastic covers for various applications. Here are the main types:

• Full covers - ideal for inspection chambers
• Openwork covers - providing ventilation and water drainage
• Telescopic covers - allowing for height adjustment
• Covers for sanitary sewage - with increased tightness
• Rainwater drain covers - with drainage holes

The selection of the appropriate cover depends on the specific installation and conditions of use.   Our experience shows that it is crucial to take into account several factors. The diameter of the manhole or pipe should be taken into account. The load class is also important. The type of sewage system is also important - sanitary or storm. The location is also important - green area or paved surface.

Our experience shows that PP dn315mm plastic covers work well in home installations. For larger facilities, we recommend models with a diameter of 400 or 425 mm. In the case of areas with high traffic, we suggest choosing covers with a higher strength class. For manholes in gardens or on lawns, lighter versions will be sufficient.

Our customers often ask about the differences between different brands.   From our observations, each has its strengths. Karmat stands out for its durability. Kaczmarek offers the widest selection of sizes and types. Wavin, on the other hand, is a leader in technical innovation. The choice of a specific brand depends on individual needs and preferences.

Practical aspects of using plastic covers

In our daily practice, we encounter various challenges related to covers. Questions about their durability and safety often arise.   Our experience shows that plastic covers are reliable when properly selected and installed.   It is crucial to follow a few rules. First, the expected loads must be precisely determined. Second, it is important to properly seat the cover. Third, it is worth regularly checking the technical condition.

We recently completed a project for a large housing estate. We used PP dn400mm plastic covers there. They worked perfectly both on pedestrian routes and in green areas. Customers appreciated their aesthetic appearance and ease of keeping them clean. What's more, these covers significantly facilitated maintenance work on the sewage network.

In the case of reorganization of urban spaces, we often encounter the need to replace covers. Plastic covers prove to be an ideal solution then. They are lightweight, which makes transport and installation easier. At the same time, their durability is not inferior to traditional materials. In one of the cities, we replaced old, cast iron covers with plastic ones. The effect was not only an improvement in aesthetics, but also an increase in pedestrian safety.

Many customers ask us about the ecological aspects of using plastic covers. From our perspective, these products have many environmental advantages. They are durable, which means they need to be replaced less often. They are also fully recyclable at the end of their life. What's more, their lightweight construction reduces CO2 emissions during transport.

At Onninen we attach great importance to the technical aspects of plastic covers.   Our products meet rigorous quality standards. We regularly conduct durability tests. Thanks to this, we are sure that the offered covers will meet even the most demanding conditions. This applies to both mechanical loads and resistance to atmospheric factors.

Our experience shows that plastic covers work well in a variety of conditions. We use them successfully in industrial installations. They also work well on farms. Their resistance to chemicals is particularly valued in manufacturing plants. Their aesthetic appearance is appreciated in parks and recreational areas.

We often come across questions about the durability of plastic covers. Our observations show that when used correctly, they serve for many years. However, it is crucial to follow the assembly recommendations. It is also worth checking their technical condition regularly. If necessary, individual elements can be easily replaced.
